SPECIFICATION forming part of Letters Patent No. 584,189, dated June 8,1897.

Application filed November 19,1896. Serial No. 612,772. (No model.)

To all whom it may concern:

Be it known that l, GEORGE B. NELSON, a citizen of the United States,residing at Redfield, in the county of Dallas and State of Iowa, haveinvented a new and useful Tool for Opening Barrels, Boxes, &c., of whichthe following is a specification.

My object is to provide a simple, strong, and durable tool speciallyadapted to be advantageously used for pulling out nails and spikes,opening barrels and boxes, stretch in g barbed fence-wire, and variousother purposes.

My invention consists in the construction, arrangement, and combinationof a solid lever having a claw at one end, a tubular handle, and asliding and rotatable multiple fulcrum, as hereinafter set forth,pointed out in my claims, and illustrated in the accompanying drawings,in which- Figure 1 is a perspective view of the complete tool ready forpractical use. Fig. 2 is a longitudinal sectional view of the differentparts combined. Fig. 3 shows the form of the sliding and rotatableannular block or multiple fulcrum. Fig. 4 shows the tool applied asrequired for stretching barbed fencewire.

The letter A designates the lever, in the form of a straight round barof iron having an integral claw B at its lower end and a piece oftube-metal C fixed on its other end by means of a rivet or in anysuitable way to fit the bore of a tubular handle and to produce anannular shoulder (Z.

F is the multiple fulcrum, consisting of a flat angular or four sidedpiece of metal having a hole which admits the top end of the lever A tobe extended therethrough before the tube 0 is fixed thereon, as requiredto connect the fulcrum with the lever, so that it can be readilyadjusted thereon by sliding and rotating to adapt it for the variouspositions and objects upon which the fulcrum is to be placed in themultifarious operations for which the tool is thereby adapted.

The hole in the multiple fulcrum F is in an eccentric position relativeto the center of its four boundary edges, so that there are practicallyfour f ulcruins difierin g in size and length relative to radial linesextending outward from the axis of the lever A. By thus producing foursides or fulcrums differing in length that are slidingly and alsorotatably mounted on the lever it is obvious the short arm of the levercan be readily varied in length by adjusting the multiple fulcrumrelative to the lever, the object upon which the fulcrum is placed, andthe object or weight to which the force of the lever is to be applied.

His a tubular metal handle open-ended and externally screw-threadedatits lower end and closed and made solid at its upper end by fittingand fixing a solid piece of round metal J therein by welding or in anysuitable Way.

After the top end of the lever A, having the tube 0 fixed thereon, isintroduced into the tubular handle H through the lower open end thereofa screw-cap K, having a central hole, (slidingly and rotatably connectedwith the lever Abefore the tube 0 is fixed to the lever,) is placed onthe open screw-threaded end of the handle to complete the tool thuscomposed of detachable parts.

To adapt the complete tool to be advantageously used as a chisel,Itemper and harden the claws B.

It is obvious that the size and weight of the tool may vary as desired.

In the practical use of the tool the manner of using it for pulling outnails and spikes and opening barrels and boxes is obvious. The jaws,when placed in proper position, can readily be driven under the head ofa nail or spike or other object by striking blows upon the head of thelever by means of the sliding tubular handle. The handle can also beadvantageously operated in the same manner for striking blows when thetool is used as a chisel for cutting wood or metal therewith.

The use of the tool as a lever for stretching barbed wire is illustratedin Fig. 4.

The manner of adjusting the rotatable and sliding multiple fulcrum asrequired in various positions relative to different objects, so as toregulate the length of the short arm of the lever and the forcerequired, is obvious, so that persons using the tool for differentpurposes at different times can readily adjust the fulcrum to availthemselves of the advantages of the multiple character of the fulcrum.

I claim as my invention- 1. In a tool for the purposes stated, astraight lever having a claw at its lower end an d a m ultiple fulcrumrotatably and slidingly combined therewith to operate in the manner setforth for the purposes stated.

2. A tool for opening barrels and boxes &c., comprising a straight roundbar or leverhaving a claw at its lower end and a fixed tube and annularshoulder at its top end, a fulcrum consisting of an annular piece orblock 16 having a hole adapting it to be rotatably and
